OK you’re the better daughter, is that what you want to hear?
FFS it’s not a competition. If that was my sister I would be asking her if everything is alright, did she have money issues etc. Unless she does this every year, in which case, what did you expect?
This The OP should have at least asked^ her sister if everything is OK. Also, there is a certain air of 'I am the better person coz I spent more on dad'' about the OP.
Of course the father is entitled to be pissed off, but the OP just comes across as rather superior........
Also, I cannot see what is wrong with banners and streamers.. 
And the comment about 'why do adults care about birthdays?' by @OwlBeThere is most odd? Why shouldn't they? Or are you one of these dreadful misers who thinks no-one over 18 should celebrate ANYthing? Or have anything that is remotely 'childish.....'
Ewwwww I loathe people like that! 
Changing the subject somewhat... Why can the OP not just put FATHER
... DF could be friend, fiance, or father. It does my head in. These dumb acronyms need abolishing!
